Heat Pumps in DeWitt, the Most Gas Heated Town in the Metro
This is the town where the heat pump case has to work hardest, because almost four homes in five here already have a gas main at the wall.

Making the heat pump case in a town that is 79 percent gas
DeWitt records 8,155 of its 10,282 occupied homes on utility gas, 79.3 percent, the highest concentration in this metro, and the DeWitt census designated place runs higher still at 83.1 percent. That is the honest context for a heat pump conversation here. Against delivered propane or oil the comparison frequently moves; against a gas main it is a longer arithmetic that turns entirely on where the balance point lands and what runs beneath it. Anyone who tells you the answer before measuring your house has not done the work. What you should be handed is a temperature, a backup plan and the published capacity figures at 5F.
What heat pump installation involves
What decides a heat pump in a gas heated DeWitt house
Two things make it a real decision rather than a closed one. First, a heat pump also cools, so the comparison is not purely against the heating bill; a household that was going to buy cooling anyway is comparing one machine against two. Second, keeping the existing gas appliance as the backup is a normal arrangement, and the alternative backup is electric resistance heat, which the Department of Energy describes as inefficient and typically expensive and says should be minimized in all heat pump installations. Where the changeover is set matters as much as the equipment. On paperwork, DeWitt's complete permit application still needs the form, the survey, the fee and a signed estimate.
One machine or two purchases
A heat pump heats and cools. If cooling was coming anyway, the comparison changes shape before any fuel is priced.
Keeping the furnace as the backup
A common arrangement here, and the changeover temperature is a design decision rather than a default setting.
The signed estimate still applies
DeWitt's application needs the form, a current survey, the fee and a signed estimate. That covers this work like any other.
The gas share DeWitt starts from, and what has to beat it
The American Community Survey 2020-2024 five-year estimates put the median year structure built in the town of DeWitt at 1963, plus or minus 2 years, and in the DeWitt census designated place at 1964, plus or minus 2 years. Of the town's 10,996 housing units, 2,054 were built in 1939 or earlier, 18.7 percent, and 8,336 before 1980, 75.8 percent. Of 10,282 occupied units in the town, 8,155 are heated with utility gas, 79.3 percent, and 1,659 with electricity, 16.1 percent. In the DeWitt CDP the utility gas share is 83.1 percent of 4,154 occupied units, among the highest in the county, with electricity at 14.2 percent.

The Town of DeWitt states that with the exception of minor repairs, a permit is needed to upgrade, modify, or install any fixed or movable improvements or structures to real property, and advises contacting the Planning and Zoning office where there is any doubt. A complete application includes the permit application form, a copy of a current survey, with photographs not accepted, a signed estimate, and the permit fee determined using the fee schedule.

The Building America Solution Center cold climate heat pump sizing guide, published by the US Department of Energy and Pacific Northwest National Laboratory with Northeast Energy Efficiency Partnerships, defines the balance point as the outdoor temperature at which heating capacity matches the home's heating demand, and states that when outdoor temperatures are below the balance point the heat pump cannot fully meet the home's heating needs without a backup heat source. It sets out four sizing approaches: size for cooling with heating secondary, size for cooling but maximize available heating capacity, size to meet most of the heating load with backup heat available, and size to meet all or nearly all heating needs. It notes that the first approach produces the warmest balance point and the fourth the coldest, and states that electric resistance backup is an inefficient and typically expensive form of heat which should be minimized in all cases of heat pump installations.

Section 25C of the Internal Revenue Code, the Energy Efficient Home Improvement Credit, now ends with a Termination subsection providing that the section shall not apply with respect to any property placed in service after December 31, 2025. The current text reflects the amendment made by Public Law 119-21, enacted July 4, 2025, which substituted that date for the previous end date of December 31, 2032.

What DeWitt homeowners ask about heat pumps
Is there still a federal credit to put toward this?
Not for work placed in service now. Section 25C of the Internal Revenue Code, the Energy Efficient Home Improvement Credit, now ends with a termination provision applying to property placed in service after December 31, 2025. Pages still advertising it are describing a rule that has lapsed. State and utility programs are a separate matter and belong with your contractor and a tax preparer.
Does it make sense at all if I already have gas?
It can, and the honest answer is specific to your house rather than to the town. What decides it is the balance point, what heats the house below it, whether you were buying cooling anyway and the capacity figures at 5F. Ask for those four and the conversation stops being about opinions.
Gas main, and still curious
